Despite being extremely heavy and requiring at least 16 strength to be worn effectively, the Looking Glass Set provides exceptionally-high defenses, notably against lightning damage, yet still performs well against other forms of elemental damage. It is the third heaviest armor set available in the game, and unlike the last two sets (Smelter Demon Set and Havel's Set), it lacks a resistance to petrification and curse, but instead has a high resistance to poison, an unusual trait for heavy armor sets. It has the second highest total Poise out of any armor set in the game, the highest being Havel's Set.
